Abstract

Apparatuses, systems, methods, and computer program products to save power in peer-to-peer communication devices associated with wireless communication networks are disclosed. Embodiments generally comprise wireless communications devices. A device may associate or connect with an access point and communicate with another device also connected to the access point. The devices may establish a direct link as part of a tunneled direct link system (TDLS) network. After establishing the direct link, the devices may negotiate a wakeup schedule, enabling both devices to enter power saving modes to conserve power. The devices may maintain the direct link while in power saving modes, enabling the devices to periodically exit the power saving modes and transfer buffered data.
